- Select the available responses.
- Program the level for monitoring.
- Program delay times for each response.
The default settings for the parameters are programmed at the factory. To accommodate unique applications and sites, the parameters may be reprogrammed with Cat ET. The screens of Cat ET provide guidance for the changing of trip points.
Note: Some of the parameters are protected by factory passwords. Other parameters can be changed with customer passwords.
Refer to the Troubleshooting Manual for programming instructions and for instructions on troubleshooting events.
The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always ON. This parameter cannot be turned off. If the system voltage decreases to the trip point or if the system voltage goes below the trip point, the ECM will generate a warning or a shutdown.
"High Engine Coolant Temperature"
The trip points for this parameter can be programmed by the customer. The shutdown response is always ON. The shutdown response cannot be turned off. If the engine coolant temperature increases to the trip point or if the engine coolant temperature exceeds the trip point, the ECM will generate a warning, a derating, or a shutdown.
"Low Engine Coolant Temperature"
The trip point for this parameter can be programmed by the customer. If the engine coolant temperature decreases to the trip point or if the engine coolant temperature goes below the trip point, the ECM will generate a warning.
The trip point for this parameter is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine speed increases to the trip point or if the engine speed exceeds the trip point, the ECM will activate an engine shutdown.
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine oil temperature increases to the trip point or if the engine oil temperature exceeds the trip point, the ECM will generate a warning or a shutdown.
"High Oil Filter Differential Pressure"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine oil filter differential pressure increases to the trip point or if the engine oil filter differential pressure exceeds the trip point, the ECM will generate a warning or a shutdown.
"Low Oil Filter Differential Pressure"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown for this parameter is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine oil filter differential pressure decreases to the trip point or if the engine oil filter differential pressure goes below the trip point, the ECM will generate a warning or a shutdown.
The trip point for this parameter can be programmed by the customer. If the fuel temperature increases to the trip point or if the fuel temperature exceeds the trip point, the ECM will generate a warning.
The trip point for this parameter can be programmed by the customer. If the fuel pressure decreases to the trip point or if the fuel pressure goes below the trip point, the ECM will generate a warning.
"High Jacket Water to Engine Oil Temperature Differential"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown for this parameter is set at the factory. The shutdown response is always ON. The shutdown response cannot be turned off. If the differential temperature of the jacket water and the engine oil increases to the trip point or if the differential temperature of the jacket water and the engine oil exceeds the trip point, the ECM will generate a warning or a shutdown.
"Low Gas Fuel Differential Pressure"
The trip point for this parameter can be programmed by the customer. If the fuel differential pressure decreases to the trip point or if the fuel differential pressure goes below the trip point, the ECM will generate a warning.
"High Gas Fuel Differential Pressure"
The trip point for this parameter can be programmed by the customer. If the fuel differential pressure increases to the trip point or if the fuel differential pressure exceeds the trip point, the ECM will generate a warning.
The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always ON. This parameter cannot be turned off. If the system voltage increases to the trip point or if the system voltage exceeds the trip point, the ECM will generate a warning.
Trip Points of the Engine Load for High Inlet Air Temperature
The trip points for this parameter can be programmed by the customer. The shutdown response is always ON. The shutdown response cannot be turned off. This feature provides a trip point between high engine load and low engine load. The trip point is used for events that involve high inlet air temperature. The trip point for the events is based on the engine load. The possible responses of the system include warning, derating, and shutdown.
If the load is greater than the trip point, the trip point for the "High Inlet Air Temperature at High Engine Load" event is used for the logging of the high inlet air temperature.
If the load is less than the trip point, the trip point for the "High Inlet Air Temperature at Low Engine Load" event is used for the logging of the high inlet air temperature.
"High Inlet Air Temperature at Low Engine Load"
The "Service/Configuration" screen of Cat ET defines the "High Inlet Air Temp Engine Load Set Point". The ECM can activate a warning, a derating, or a shutdown if the inlet air temperature increases to the trip point or if the inlet air temperature exceeds the trip point during the low load operation that is defined.
"High Inlet Air Temperature at High Engine Load"
The "Service/Configuration" screen of Cat ET defines the "High Inlet Air Temp Engine Load Set Point". The ECM can activate a warning, a derating, or a shutdown if the inlet air temperature increases to the trip point or if the inlet air temperature exceeds the trip point during the high load operation that is defined.
The trip point for this parameter can be programmed by the customer. The ECM will activate a warning if the fuel pressure increases to the trip point or if the fuel pressure exceeds the trip point.
Some of the programmable parameters are dependent on the status of an ECM output before the parameters are allowed to function. Some of the parameters are allowed to function after the crank terminate relay has been energized for more than 30 seconds. Other parameters are allowed to function after the output for the fuel control relay is energized. Some parameters are not dependent upon any conditions.
The conditions are designed to eliminate false events during start-up if the customer has programmed a delay time to zero.
If the trip point for a shutdown is programmed to activate before the trip point for a warning, the engine will shut down and the warning will not be activated.
Customer Communication Module (CCM)
By using PC software with a customer communication module, a customer can connect to an ECM remotely. The customer communication module will perform the following functions:
- Display the ECM summary.
- Display the parameters.
- Display active diagnostics.
- Display logged diagnostics.
- Display active events.
- Display logged events.
- Display the current totals.
- Display the status flags.
